Creation of 4x3 posters

Maxwell -

Hello everyone,
I actually want to create a poster that is 4 meters by 3 meters (4X3) and I would like to know what scale I should work at.
Additionally, what resolution should I export it at?
I work with Corel Draw and often export in PSD or PDF.

Thank you for your help.

Hello Maxwell,

It is indeed 30 x 40 cm for the workspace or the size of the image.

Have a good day.

it's 30x40 at 300 dpi.
When printing, to produce the x10 ratio on the size, the resolution will be divided by 10: that is, 30 dpi, which is more than sufficient for a very large image.

What to remember: the larger the print size, the lower the resolution can be: because you look at the print from a distance and the dots can be larger.

Negative! Well, yes and no, let me explain:
Consider that 72dpi should be the full-size definition to have something correct (not pixelated). Below that, the quality becomes poor. 30 dpi is really disgusting...
If you are working at 1/10 scale, then use 720dpi.
You can work at 300dpi at a quarter (1/4 scale = 100x75cm), which results in 75dpi at full size.

At best, for a 4 by 3, because it's viewed from very far away, you can afford to work with a final definition of 30dpi.

I still recommend always keeping a definition of at least 72dpi!
